Possible Cause

Display use for
video recording,
excessive flash
use, or Display
Brightness set to
High, increases
the rate of
battery drain.
The NiMH
batteries you
are using were
recharged
incorrectly, or
have drained on
their own
because they
have not been
used lately.
Battery

is inappropriate
for the way the
camera is being
used.
Rechargeable
batteries are not
inserted.
Batteries are
already
charged.
Troubleshooting and Support
Solution
See Extending Battery Life on
page 150.
NiMH batteries are not fully
charged when new, and they
discharge over time whether or
not they are installed in a
camera. Batteries that are new
or have not been charged
recently must be recharged to
reach full capacity (see
page 155).
See Performance per Battery
Type on page 152.
Install NiMH batteries. Lithium
and Alkaline batteries cannot
be recharged.
Battery charging will not start if
the NiMH batteries were
recently charged. Try charging
them again after they have
drained a while.
